Feature: Invoice Management in DAOs with Trustless and Trusted Payment Options.
The Invoice Contract is a specialized smart contract designed to streamline the management of invoices within a DAO (Decentralized Autonomous Organization) framework. This contract offers a unique blend of functionalities, catering to both trustless (on-chain) and trusted (off-chain) payment scenarios, thereby offering flexibility and adaptability to a wide range of use cases.
Key Aspects of the Invoice Contract:
1. Flexible Invoice Creation:
Any address, irrespective of its Governance token holdings or pool status, can act as an invoice payer.
Invoices can be public (with an empty whitelist) or restricted to specific addresses.
Invoices remain active until paid, canceled, or upon reaching their expiration block.
2. On-chain Invoice Payment:
Facilitates direct on-chain payments for invoices using either ERC20 tokens or ETH.
Invoices include essential details like payment amount, expiration block, and token type for payment.
Payments are validated against the invoice’s active status and payer’s whitelisting.
3. Off-chain Invoice Payment (Trusted Scenario):
Managed via a backend solution for verifying off-chain payments.
Addresses with the
SERVICE_MANAGERrole in the Service contract can mark invoices as paid, bypassing on-chain payment.
Offers a more flexible approach for handling payments outside the blockchain.
4. Invoice State Management:
Invoices can be in various states: Active, Paid, Canceled, or Expired.
State changes are tracked and managed to ensure accurate and timely updates.
5. Comprehensive Event Logging:
Key actions like invoice creation, payment, and cancellation emit specific events for transparency and traceability.
These events are crucial for auditing and record-keeping within the DAO.
6. Administrative Controls:
Specific roles and permissions govern who can create or cancel invoices, ensuring proper authorization and control.
The system allows for pool-specific invoice management, aligning with the decentralized nature of DAOs.
Compliance and Regulatory Adherence:
The Invoice Contract integrates seamlessly with compliance protocols, ensuring that all transactions adhere to regulatory standards, such as KYC and AML. This integration is pivotal in maintaining the legality and integrity of financial operations within the DAO.
